Nov. 24, 1931. T. w. RIEKE BARREL Filed July 16, 192'? Patented Nov. 24, 1931 yUNITED STATES PATENT OFFICE THEODORE W. RIEKE, F AUBURN, INDIANA, ASSIGNOR TO RIEK METAL PRODUCTS CORPORATION, OF AUBURN, INDIANA, Al CORPORATION OF INDIANA BARREL Application med July 16,

draining the barrel when inverted.

Another object of the invention is to provide an improved seal Which vmay be so related with the plug that any unauthorized opening or tampering with the plug will be readily indicated.

Other objects of the invention will be apparent to those skilled in the art to which my'invention relates from the following description taken in connection with the accompanying drawings, wherein Figure 1 is a fragmentary plan view of one Wall of a barrel showing the up-set wall ready to receive a bung ring Figure 2 is a' section on the line 2-2 of Figure 1.

Figure 3 is a detail top plan .view of a bung ring constructed according to this in.- vention.

Figure 5 is a transverse section, enlarged,

is a section taken through the vthrough the ring and barrel wall.

Figure 6 is a view similar to Figure 5 with the plug in position and showing lin dotted lines one form of sealing cap.

erably provided with a flange 16. 17 indicates an opening formed in the wall 15 and about the opening is disposed an initially raised or distended portion 18. The ring 19 and fastening means therefor are of the type wherein the metal of the barrel wall folds around the fiange on the ring and thus forms an annular groove or recess between the folded portions of the metal and the exposed surface of the barrel, which groove receives the free edge of a sealing device, as Will later appear. In the construction of ring and fastening means therefor herein shown as one example, the ring 19 comprises an annu lar body part 19v having at one end a ra- .dially extending ange 20 the outer marginal edge portion of which is providedwith serrations 21. The inner end of the body portion 19 of the ring is provided with spaced radial notches or recesses 22 of Asufficient depth to extend into the plane of the inner face of the barrel head 15, so that when the barrel is inverted, its fluid contents may freely flow through the notches 22 into the ring 19 and outwardly through the bung.

From Figure 5' it will be noted that the flange 20 of the bung ring is sealed and mounted in fixed relation to the opening 17 by folding over or overturning the lportion 18 about the flange 20 and by crimping the metal of the portion 18 into the serrations 21 of the ange 20. Thusa relatively tight joint and seal are provided between the wall l5, and the ring body 19. The interior of the ring 19 is threaded from end to end to detachably receive therein a threaded plug 23 adapted to be secured into the ring. The construction of the ring flange and method of fastening the ring-in position is disclosed in my co-pending application Ser. No. 86,255, filed February 5, 1926. The plug 23 has an outstanding annular shoulder or flange 24 adapted to be turned or screwed down against the rolled over portion of the flange 18.v A gasket or packing ring 25 may be interposed between the flange 18 and the shoulder 24. The plug 23 is provided with an outer angularly faced portion providing a nut by means of which the plug may be readily turned. The plug 23 may also have a non-circular which may be attached a safety device to prevent loss of the plug from the barrel when the plug is released from the ring 19.

From Figures 5, 6 and 7 it will be apparent that the portion 18 when folded about the `flange 20 provides the annular groove 28 extending entirely around the bung and beneath the serrated flange 20. This groove 28 is utilized for interlocking and sealing a cap 29 to the wall 15 and in operative relation to the plug 23 when the latter is in place. This sealing cap preferably comprises a hollow body part of relatively thin, flexible metal which at its open end is provided with an inwardly extending flange 30. In Figurey 6 I have, in dotted lines, shown the cap in its distended form ready for application to the wall 15. As shown, the flange 30 is slightly turned inwardly so that when the cap 29 is forced in a direction toward the wall 15, the flnage 30 will bend or Hex inwardly and thus slide into the groove 28, and thus become interlocked with the lateral portion 18 of the barrel wall. The cap 29 may be in the form, shown in Figures 6, 7 and 8 wherein the outer end of the cap is provided with an overhanging flange 31, which envelops the shoulder portion 24 of the plug 23 and approaches the nut or central portion of the plug.

In Figures 9 and 10 t-he outer end of the cap, which is indicated at 32 is closed and completely covers the plug 23, being pref erably provided with an outwardly stepped closure wall 33 extending entirely across the outer end of the cap. The cap 32 is in `both instances held in place by pressing the cap inwardly against the wall 15 and causing the yieldable flange 30 to move into the groove 28 and effect an interlock with the head.

As the flange 31 overlies the plug, unscrew` G it has been tampered with; and likewise, a

breaking away of a portion of the cap or distorting it will indicate that the plug 23 has been removed or attempt made to -remove it. As a result of the effec-t incident to tampering with the cap of the plug or both, the cap provides an effective seal or'guard for the plug; at the same time due to the ilexibility and thinness of the cap it can be readily removed by a person who has authority to remove the plug 23.

It will be noted that the cap 29 ts snugly around the flange 24 and upon the exposed face of the plug, so that slightdanger ex ists of the cap being broken away or distorted in shipment of the barrel or container.

It is obvious that various changes and modifications may be made in the details of construction and design of the above specilivcally described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claim.

What I claim is:

lIn a barrel having'a pressed-in bung ring, a sheet metal wall formed with an opening and provided with a pre-formed flange about said opening on one side of said wall, a bung ring arranged to be positioned from the opposite side of said wall and comprising a body portion and an outstanding flange at its outer end having its outer face fitted against said pre-formed flange, whereby the latter provides a seat for a gasket, the metal of the wall adjacent to and surrounding said pre-formed flange being folded around the side edges of said ring liange and inwardly therebelow into concentric relation to said body portion and above the plane of said sheet metal wall, the inner end of said bung ring extending beyond the plane of the inner surface of said wall and formed with notches to a depth substantially co-incident with said plane for permitting complete draining of the barrel.

In testimony whereof, I have hereunto subscribed my name.

THEODORE W. RIEKE.
